I don't know if this is the correct mod to post it in, or if it's maybe post-processing, but i keep having, fps drops every couple of seconds,
this line when debug is enabled does seem to point that out, when the mini-freeze happens, this line gets to around 3-5/0/150-160

if you need anything else, please don't bother asking ^^ the game is sadly unplayable like this, maybe its conflicting with other mods on the save?

It's likely mod conflict. May you post your save?

Having mini freeze like that is definitely not normal. It tops at 0.3-0.5/0/1-3 range on my 8600K. When the mod is not busy, it run under 0.01/0/under 0.5.

P.S. all bugs post in ERM. The post-process mod just call ERM indexes when the game loads.

Can you try with enabling only ERM mods to check whether it still causes mini-freeze?

Hey, i found the issue, im living in an island, and the mobs cant reach it, it laggs because hundreds uppon hundreds of biters, and other enemies, stack in a big clump and try to pathfind every couple of frames, even though they cant reach it ^^ when i clear the clumps the fps drops stop

I still want to have your map to test. The enemy should have switched to aerial attack if they can't attack you on an island.
